Your Guide to Properly Rendering a Wall

There is no denying that properly rendering an exterior wall is incredibly important. After all, it is this process alone that will ensure that no water will enter the interior of your home or any other building. Now, the good news for you is that this is a task that can be managed by yourself. At the same time, you do need to be aware of the proper process so that you can do it right. If you are curious about what this is, you will find all of the information that you need, below:

Start the Prep Work

Now, it should go without saying that if you want professional results, then you need to use the best rendering tools available to you. So, this really should be your first order of business. Once you have managed this, you will need to move onto prepping the exterior wall. If the wall hasn’t been newly built, then you will need to clean it thoroughly. Any loose paint, dust, debris, or plants need to be carefully removed so that the wall is completely flat. This can be done by scrubbing followed by hosing down the surface. You should wait until the wall has dried a bit before continuing with the next stages.

Getting the Mix and Wall Ready

When getting the mix set up, it is important to only make what you will be using in the next 30 to 40 minutes. This will help to cut down on any waste. Also, you should make it a point to make all of the measurements by hand and to use the same gauge vessel. This, too, will increase the level of accuracy. Depending on the size of the wall, you may want to use a screed batten as this can make it easier to break up a larger wall into more manageable portions. Not to mention, it also gives you a starting point and can help make sure that you apply the same thickness all over.

The First Layer

Then, it is time to apply the first layer. You should try to keep the thickness of the first layer to around 4 to 6mm for the best results. At this thickness, you will find that the render will adhere to the wall more quickly. After this, it is time to scratch the first layer. This can be accomplished with the help of a comb-like tool although a screwdriver can work just as well. The main goal here is to create grooves in the mix so that the second layer will adhere to it better.

The Final Steps

After the consecutive layers have been applied, the battens should be removed and smoothed out. Once the wall has dried out a little, you will need to use a float to smooth out the surface further. This process ensures that all of the air holes are closed up. If you really want a professional look, use a slightly damp car sponge after that step to wipe down the wall, sealing it up further.

Now you are aware of just what it is that you need to do to properly render a wall. The only thing that you need to do after this is to get your tools and start working.
